Concept explainers
(a)
Interpretation:
The difference between the average kinetic energy of reactants and products is to be discussed.
Concept introduction:
Average kinetic energy depends on the temperature of the system.
It is given by:
When there is a release of energy in a reaction, the temperature of the system rises which increases the average kinetic energy.
(a)
Answer to Problem 3E
The average kinetic energy of products is more than reactants.
Explanation of Solution
When methane reacts with oxygen, carbon dioxide and water are produced. This process is exothermic. So, a large amount of energy is also released which increases the temperature of the system.
Hence, products have more average kinetic energy than reactants.
(b)
Interpretation:
The information given by the molecular view of reactants and products is to be given.
Concept introduction:
The molecular view shows the geometry of molecules. It shows how the molecules are interacting. It shows the bonds which are breaking and the bonds which are creating.
(b)
Answer to Problem 3E
The molecular view will show how the bond formation and cleavage taking place in the conversion of reactants to products.
Explanation of Solution
The molecular reaction of the given equation is:
It shows the bond between carbon and hydrogen is breaking and two carbon-oxygen multiple bonds are forming.
